Inspection of Unmixed By-Products. 

 The Oil Cake Meals (Cottonseed, Linseed, and Peanut). 



The average quality of cottonseed meal was found to be sUghtly better than for the 

 preceding year. Increased sales in meal guaranteed to contain 43 per cent of protein 

 were noted. Average results show but two brands below their protein guarantee, and 

 these only a fraction of 1 per cent. Cottonseed meal is sold by manufacturers and 

 wholesalers on the basis of its protein content, the different grades containing 36, 38J, 

 41 and 43 per cent protein. The average retail ton price of the different grades col- 

 lected follows: — 



36 per cent protein ............ $52 31 



41 per cent protein . . . . . . . . . . . . 53 33 



43 per cent protein . . . . . . . . . , . . 55 50 



These figures indicate that retailers in selling are governed more or less closely by the 

 price of purchase. The low protein meals (36 per cent) contain more of the indi- 

 gestible fiber and are less economical than the better grades. 



Linseed meal was better than for 1921, when the quality of the seed crushed yielded 

 a product containing less protein and more fiber than normal. 



But one lot of peanut meal was found. It compared favorably in composition with 

 the best grade of cottonseed meal, and, at the price asked, could be considered a satisfac- 

 tor}' substitute. In niaking the better grades of peanut oil the shell is removed before 

 crushing, and the resulting meal is much to be preferred to the meal containing the 

 kernel and shell crushed together. The sample examined was of the former quality. 



The Corn Gluten Products (Gluten Meal and Gluten Feeds). 



Diamond corn gluten meal, the only brand offered in Massachusetts, is a pure corn 

 by-product consisting largely of the protein of the corn kernel after the elimination of 

 considerable of the starch and most of the bran and germ. It was sold at about the 

 same price as cottonseed meal, for which it could be substituted in a ration. 



Gluten feed is gluten meal plus corn bran, some corn germ and corn starch. The 

 Success brand of gluten feed reported in the tabulation, while made by a somewhat 

 different process and having a different appearance, has approximately the same feed- 

 ing value. All samples collected practically conformed to or exceeded their guarantees. 



Brewery, Distillery and Yeast Factory By-Products. 



Farmer Jones distillers' grains, the only brand found, was of excellent quality. 



The three brands of dried brewers' grains showed a wide variation in protein con- 

 tent, the Bull brand falling decidedly below its guarantee. 



Yeast grains, a product from the Fleischmann Company, are the dried residues 

 derived from a mixture of several grains and cereal by-products used in propagating 

 the yeast plant. The sample reported somewhat resembles low^-grade brewers' grains 

 in composition and feeding value.
